Suggestions on DAC/network audio player for Valve Audio/Sonor Audio setup

I'm in the process of replacing stolen Steinhart + Marantz CD player with Valve Audio Exclame 150 and Sonor Audio Claros 6.2. I need advice on a sound source capable of streaming Tidal, Deezer, Google Play. No requirement for CD.
This is something I know very little about. I have a Chromecast Audio which has optical out so I guess that can take care of accessing these sound sources and bypassing the Chromecast DAC.
I have a budget of around R8k
Thanks
